1. Impact of reproductive and productive rates on levels of inbreeding and genetic gain of pigs through data simulation
ABSTRACT The objective of this study was to evaluate the impact of farrowing and mortality rates on inbreeding levels and genetic gain through data simulation. Data came from two real populations A and B, composed of Pietrain and Landrace breed pigs, respectively. To generate the simulated populations, a Fortran-language simulator was developed using the (co

2. Study of natural ventilation in a Gothic multi-tunnel greenhouse designed to produce rose (Rosa spp.) in the high-Andean tropic
Resumo Nas regiões tropicais, a produção de plantas ornamentais é desenvolvida exclusivamente em estufas plásticas ventiladas de forma natural, o que significa que em algumas ocasiões microclimas inadequados são gerados com altas temperaturas e umidade que limitam o desenvolvimento produtivo das plantas. O objetivo deste trabalho foi estudar os fluxos

3. Strategies to control inbreeding in a pig breeding program: a simulation study
RESUMO: O objetivo deste estudo foi avaliar, por meio de simulação de dados, o impacto das restrições no número máximo de irmãos completos e meios-irmãos selecionados para machos e fêmeas no nível de endogamia e ganho genético do rebanho. Os dados originais são provenientes das populações reais A e B, compostas por suínos da raça Pietrain e

4. PERTINENCE CURVES IN FUZZY MODELING OF THE PRODUCTIVE RESPONSES OF BROILERS
ABSTRACT The selection of the type of fuzzy systems pertinence curve allows a better representation of the mathematical model and a smaller simulation error. We aimed to study the effect of pertinence curves in fuzzy modeling of broiler performance, created in different production systems. For the development and testing of fuzzy models, three commercial avi

5. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

7. A simulation model to evaluate the economic consequences of insemination programs in dairy herds: timed artificial insemination and sex-sorted semen
ABSTRACT The objective of this study was to develop a simulation model to analyse the technical, economic, and financial performance of using different reproductive strategies in dairy herds. Strategies simulated were: artificial insemination (AI) using conventional semen after oestrus detection (AIC), AI using sex-sorted semen after oestrus detection (AIS),

8. Simulation-Based Analysis of Additive Manufacturing Systems for Fuel Nozzles
ABSTRACT: Additive manufacturing technologies have the potential to revolutionize manufacturing, allowing for the production of ever more complex products and supporting the creation of strategic competitive advantages to certain industries. Recent investments in additive manufacturing systems show that operational plants are close to become reality. In this

9. Work in process level definition: a method based on computer simulation and electre tri
This paper proposes a method for defining the levels of work in progress (WIP) in productive environments managed by constant work in process (CONWIP) policies. The proposed method combines the approaches of Computer Simulation and Electre TRI to support estimation of the adequate level of WIP and is presented in eighteen steps. The paper also presents an ap

10. Desempenho de modelos de estimativa da radiação solar na região do Triângulo Mineiro / Performance of methods for estimating solar radiation in the region of Triângulo Mineiro
A radiação solar é determinante sobre o comportamento climático global e os fenômenos meteorológicos, sendo os dados exigidos em muitas aplicações e nas diferentes áreas de estudos. Em estudos agronômicos, o saldo de radiação ou de energia representa a quantidade de energia que está disponível para os processos de evapotranspiração, fotossín

11. Critical points in logistic growth curves and treatment comparisons
Several biological phenomena have a behavior over time mathematically characterized by a strong increasing function in the early stages of development, then by a less pronounced growth, sometimes showing stability. The separation between these phases is very important to the researcher, since the maintenance of a less productive phase results in uneconomical

12. Proposta de um procedimento para a modelagem de sistemas de controle de edifícios inteligentes utilizando a rede de Petri colorida. / A procedure for modelling the control system in intelligent buildings based on colored Petri nets.
Technological advances in recent decades have motivated the development of intelligent buildings, aimed at creating environments more productive for the occupants, economically advantageous for the owners and environmentally correct. New ways of interaction between users and the buildings systems are emerging from these kinds of systems, which are not adequa
